GENERAL DESCRIPTION
O2Micro's OZ992 Smart ACPI/SCI (System Control Interrupt) General Purpose Input/Output unit allows OEMs transform their legacy systems ACPI compliant systems supporting extra inputs. Regular core logic chipsets, such Intel 430TX/BX ACPI compliant embedded controllers have limited allowance GPIO input signals system. OZ992 provides bridge between chipsets rest system allow system designers cost-effective improvise such deficiency. OZ992 provides GPIO signals regular slave mode. addition, OZ992 allows System Control Interrupt (SCI) input transitions written system's embedded controller master mode. OZ992 provides perfect solution leading notebook vendors stay ahead competition. OZ992 SMBus compliant ACPI GPIO with Programmable General Purpose I/Os pins flexible variety functions such programmable inputs/outputs, SMB/SMI interrupt service, power-saving, modularized hardware Auto Flash (ALF) status display. OZ992's other features include hardware-driven speaker alarm output. Pentium x86-based system compatible device, OZ992 Smart ACPI GPIO highly costeffective practical solution today's notebook palmtop computers, pen-based data systems, personal digital assistants, portable datacollection terminals.

DESCRIPTION
Name SMBCLK SMBDATA PWRGD Type Input Drive Definition SMBus Clock Input SMBus Clock Input SMBus protocol communication. SMBus Data Input/Output 12mA SMBus Data Input/Output SMBus protocol communication. Host System Power Good This indicates that host system's power, including Core Logic chipsets, stable. Before host system's power stable, this input will tri-state output pins from OZ992. Interrupt embedded controller will signify OZ992 when activated been serviced. This used with master mode only. General Purpose I/Os [6:5] Fully programmable GPIOs that used variety dedicated specific functions. Pins GPIO[17:16] default inputs. They programmable function either GPI[17:16] inputs GPO[17:16] outputs. Refer GPIO[19:16] Config.1&2 Registers more details GPIO Config. Tables (section 5.0) input/output selections. General Purpose I/Os [8:7] Fully programmable GPIOs that used variety dedicated specific functions. Pins GPIO[19:18]/TEST[1:0] default inputs. They programmable function either GPI[19:18] inputs GPO[19:18] outputs. Refer GPIO[19:16] Config.1&2 Registers more details GPIO Config. Tables (section 5.0) input/output selections. During regular usage, pull-ups should connected GPIO[19:18]/TEST[1:0] ensure regular OZ992 operation. Alternative uses GPIO[19:18] TEST[1:0], which provide proprietary OZ992 test modes.
